Relationship between US Dollar Index and Gold

Gold is an asset. As such, it has intrinsic value. However, that value can fluctuate over time, sometimes in a volatile fashion. As a rule, when the value of the dollar increases relative to other currencies around the world, the price of gold tends to fall in U.S. dollar terms. It is because gold becomes more expensive in other currencies. As the price of any commodity moves higher, there tend to be fewer buyers, in other words, demand recedes. Conversely, as the value of the U.S. dollar moves lower, gold tends to appreciate as it becomes cheaper in other currencies. Demand tends to increase at lower prices
